Organic molecules, like proteins, lipids and carbohydrates, perform several functions for living organisms. Noteworthy functions are the structural function (as part of the material that constitutes delimits and maintains organs, membranes, cell organelles, etc.), the energetic function (chemical reactions of the energetic metabolism), the control and informative function (genetic code control, inter and intracellular signalling, endocrine integration) and the enzymatic function of proteins (facilitation of chemical reactions).
